We find strong evidence of hysteresis
in cases A, B, and E, indicating the existence of a first-order phase transition,
in correspondence to
the thick blue lines in Fig. REF .
By comparing the behavior in the segments A and B, the wider mass range over which hysteresis exists
in the former case seems to indicate that the strength of the phase transition grows as \(am_0^f\)  increases,
so that we expect that the first order lines persist all the way to the infinite mass case,
for which either the fundamental or antisymmetric fermions are non-dynamical (quenched).
In the heavy mass limits, this is consistent with recovering earlier results in the literature [1]}, [2]}.
